The energization of the coils having been in the meantime interrupted, the springs will expand and acting on the return-bar, will move it so as to return the armature-bar automatically to its initial position.

It will be noted by the operation described that the armature-bar itself simply moves the return-bar from its position the force required to do this being negligible, while the impelling force of this return-bar sets the spring to tension, which tensioning togetherI with the action of gravity as described, returns the parts to their initial position. In other' words, no expenditure of energy is necessary excepting the almost negligible one of moving the return-bar. The construction of the return-bar or flip-hap is simple and it may be readily applied.

By my improved device a very eflicient penetration of the record is secured, and the rotation of the dial is not interrupted by the sticking of the needle in its penetrating position. Furthermore, the lining of the armature with paper layers to prevent the action of the residual magnetism is done away with, thus facilitating the manufacture and decreasing the cost of the same. The paramount advantage, however, is the securing of the parts in their normal position after their actuation so as to be always ready for their proper manipulation.

I do not wish to be limited to the precise form shown in the practical embodiment described, since changes may be made without departing from the spirit of my invention.

Having thus described my invention, I claim as neuT and desire to secure by Letters Patent.

l. In an electric watchmans clock, a plurality ol' electrically-operated armature-bars, and a return-bar passing over all oi' said armature-bars and adapted to return the armature-bars automatically to their original position after their actuation.

2. In an electric watchmans clock, having a plurality of electrically-operated armature bars, a return-bar arranged some distance from the armature-bars so as not to be in contact therewith but in the path of movement of the armature-bars, and a spring some distance away from the return-bar not in contact with it but in the path oi' movement of it, so as to be tensioned by the return-bar.

3. In an electric watchmans clock, having a plurality of electrically-operated armaturebars, means normally not in contact with the bars adapted to return the bars automatically to their original position after their actuation.

4. In an electric watchmans clock having a series of electrically-operated armature bars, a pivoted return-bar suspended freely and crossing all ol the armature-bars.

5. In an electric watchmans clock having a plurality of electrically-operated armaturebars, a gravity controlled return-bar extend ing across all of said armature-bars, means normally out oi' contact with the return-bar acting on said return-bar when brought in contact therewith to press said return-bar in the direction ol' the armature-bars- 6. In an electric watchmans clock, the combination with the armature-bars, ol a return-bar comprising an elongated main portion having end members extending laterally therefrom, said members being freely suspended whereby the main portion is adapted to return to its original position alter being moved away from it, and in returning to its original position to cause the armature-bars to be moved therewith.

In testimony, that I claim the vforegoing my invention, I have signed my name presence oiA two subscribing witnesses.
